A negative probability table problem of heating number in FENDL-3.1d ACE fileenghttp://id.nii.ac.jp/1657/00080860/Conference PaperKonno, ChikaraKwon, SaeromWe found out that probability table (p-table) data for heating number in the FENDL-3.1d ACE files for 33 nuclei included negative values. Thus we investigated its reason in detail. As a result, it was specified that the reason was that partial KERMA factors of the radiative capture reaction became too large, because the energy-balance was broken or NJOY did not treat secondary gammas of a special format. We proposed two solutions for this issue; 1) to modify NJOY so as to calculate partial KERMA factors with the kinematics method, 2) to set p-tables for heating number to “1.0” or average heating numbers. New ACE files of FENDL-3.1d produced with the two solutions had no negative p-tables for heating number.Proceedings of SNA+MC20203203252020-11none2020-11-04
